plus() method of a ChronoZonedDateTime class used to returns a copy of this date-time with the specified amount added to date-time. The amount is typically Period or Duration but may be any other type implementing the TemporalAmount interface.
Syntax:
public ChronoZonedDateTime plus(TemporalAmount amountToadd)
Parameters: This method accepts one single parameter amountToadd which is the amount to add, It should not be null.
Return value: This method returns ChronoZonedDateTime based on this date-time with the addition made, not null
Exception: This method throws the following Exceptions:
- DateTimeException: if the addition cannot be made
- ArithmeticException: if numeric overflow occurs
Below programs illustrate the plus() method:
Program 1:
// Java program to demonstrate // ChronoZonedDateTime.plus() method import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;
public class GFG {
public static void main(String[] args)
{
// create a ChronoZonedDateTime object
ChronoZonedDateTime zonedlt
= ZonedDateTime
.parse(
"2018-12-06T19:21:12.123+05:30[Asia/Calcutta]" );
// add 10 Days to ChronoZonedDateTime
ChronoZonedDateTime value
= zonedlt.plus(Period.ofDays( 10 ));
// print result
System.out.println( "ChronoZonedDateTime after"
+ " adding Days:\n "
+ value);
}
} |
ChronoZonedDateTime after adding Days: 2018-12-16T19:21:12.123+05:30[Asia/Calcutta]
